Bel Power Solutions point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus Architecture (IBA). The YNV12T16 non-isolated DC-DC converters deliver up to 16 A of output current in an industry-standard, through-hole (SIP) package. They operate from a 9.6 to 14 VDC input and are ideal choices for Intermediate Bus Architectures where point-of-load power delivery is generally a requirement. In addition, they provide a resistor-programmable regulated output voltage of 0.7525 V to 5.5 V. The Y Series of non-isolated DC-DC converters provides exceptional thermal performance, even in high temperature environments with minimal airflow. This is accomplished through the use of circuit, packaging and processing techniques to achieve ultra-high efficiency, excellent thermal management and a very sleek body profile. The low body profile and the preclusion of heat sinks minimize impedance to system airflow, thus enhancing cooling for both upstream and downstream devices. The use of 100% automation for assembly, RoHS lead-free solder and lead-solder-exempted coupled with advanced power electronics and thermal products are available design, results in a product with extremely high Delivers up to 16 A (88 W) reliability.
